Quick Summary

Isinglass is a gelatinous substance derived from the air bladders of fish, primarily sturgeons. It is a pure, semitransparent, and whitish material.1

Historically, isinglass has been used for several purposes:
* Clarifying agent: It is employed to clear liquids, particularly in brewing and winemaking.
* Foodstuffs: It can be used in the preparation of jellies.
* Adhesives: It serves as a component in glue production.

The term "fish glue" can also refer to isinglass or a strong adhesive made from heating fish skins, fins, and bones. "Japanese isinglass" is another term for agar.23
